5.3 Pinpoint location

5.3.1 Introduction

This application primarily serves to pinpoint a pre-located leak. In addition, the application is always useful when noise measurements are to be made

at a number of measuring points and the minimum levels compared to one another. To mark the loudest measuring points, suitable objects or marking spray should be

available.

5.3.2 Procedure

There are different ways to proceed with the pinpointing. The choice of method depends on the accuracy with which the leak could be pre-located and whether the path of the pipeline is known.

two possible variants:

“10-point search”

“Free search”

Before the measurement, the user sets 10 evenly spaced measuring points along a certain section. During pinpointing, ten individual measurements are taken successively at these points. At the end, the results are compared on the screen and the loudest measuring point is marked. Then the search can be narrowed to the area around the marked point and repeated.

The user does not define the individual measuring points in advance, but always selects the next measuring point freely after starting pinpointing.

Connect the desired microphone and switch on all participating devices. In the status bar of the screen, a pictogram indicates which mode of operation is

currently set for the mute button:

5.4 Pipe locating

5.4.1 Introduction

This application is primarily used for acoustic pipe location and pipe path location. During this process, a defined acoustic signal is transmitted to the pipe at an accessible location, for example using the “RSP-3” device from SebaKMT. The HL 7000 records this signal at the surface of the earth.

In addition, the application is always useful when noise measurements are to be made at a number of measuring points and the maximum levels compared to one another.

To mark the loudest measuring points, suitable objects or marking spray should be available.

5.4.2 Procedure

There are different ways to proceed with the pipe location.

two possible variants:

“10-point search”

“Free search”

Before the measurement, the user sets 10 evenly spaced measuring points along an intended section. During pipe location, ten individual measurements are taken successively at these points. At the end, the results can be compared on the screen and the loudest measuring point is marked. The user performs another 10point search. Ideally, the sum of the marked, loudest measuring points indicates the course of the pipe in question.

The user does not define the individual measuring points in advance, but always selects the next measuring point freely after starting pipe location.

Connect the desired microphone and switch on all participating devices. In the status bar of the screen, a pictogram indicates which mode of operation is

currently set for the mute button:

5.5 Tracer gas detection (H2 sensor)

5.5.1 Introduction

With a connected gas sensor, the HL 7000 system can be used for leak detection with a tracer gas.

In this location method, at an accessible point in the damaged pipe, tracer gas that contains H2 is introduced. The gas escapes from the line at the leak and emerges above the leak. The user performs a series of individual measurements, one after the other, in the area of the pre-located leak or along the pipeline. Here, the H2 concentration of the air near the ground is determined. At the location of the highest measured gas concentration, the leak is suspected.

5.5.2 Procedure

Mount the H2 sensor on the CS-7 carrying pole and switch on all involved devices.

Note that the PAM H-7 gas sensor requires a warm-up period of 10 minutes after switching on before reliable measurements are possible.

In the status bar of the screen, a pictogram indicates which mode of operation is currently set for the mute button:

Mute button works as a “switch”

Mute button works as a “push button”

If necessary, change the mode of operation in the system settings (see page 62). Then proceed as follows:

Step

Description

In the HLE 7000 Start menu, tap the H2 sensor button.

Result: The menu for tracer gas location opens.

Muting is active, meaning that there is still no measurement.

Start the measurement with the mute button on the HLE 7000 or the CS-7.

Result: Muting is switched off. The measured H2 concentration is displayed

on the screen.

Perform a zero point reference calibration:

 Make sure that the gas sensor is calibrated in “clean” air without tracer gas.  In the screen, tap the button.

Page 59

Performing measurements

Step

Description

Result: The device adjusts to the natural, local H2 concentration. The

displayed value should be close to zero. The zero point calibration remains valid until it is cancelled with the button

or the menu is closed.

The mute button interrupts the measurement.

Go to the first measuring point. Mark the measuring point with an object.

Use the mute button to resume measurement. Swing the gas sensor slowly to the left and to the right just above the ground.

Result: The measured H2 concentration is displayed on the screen. At the same time, the gas concentration is indicated acoustically by a rising or falling tone on the headphones. In the histogram, the course of the measurement is recorded as a curve.

Wait until the displayed value has settled at a constant level.

The mute button interrupts the measurement.

Result: The headphones are muted. The screen freezes.

Go to the next measuring point. Use the mute button to resume the paused measurement. Swing the sensor slowly to the left and to the right just above the ground.

Result: The measured gas concentration is displayed. The measurement curve is continued.

Use the mute button to interrupt measurement again.

Take further measurements.

In this way, you gradually approach the point where the greatest quantity of the tracer gas escapes from the ground. You have found the leak position as soon as no higher value can be measured.

The display area contains the following information:

Element

Description

H2 concentration

The displayed value is dimensionless. The default is a scale from 0 to 1000. Smaller scales can be set.

Histogram

In the diagram, the recorded values of the measurement are displayed as a continuous curve.

X-axis … time in s Y-axis … H2 concentration

Warm-up time

This timer shows how much time has elapsed since the start of the measurement and whether the measurement results can already be considered reliable.

5.5.4 Tools

The buttons on the right edge of the screen provide the following tools:

Zero point calibration

When you tap this button, a zero point calibration is performed. Zeroing the device adapts it to the naturally occurring H2 concentration in the air at the

site. During the measurement, this concentration is then subtracted from the recorded values. As a result, the displayed H2 values are “adjusted” and comparable.

The button turns off the zero point calibration function.

Scaling

With this button you can gradually reduce the displayed area. This can be helpful to make low values in the bar graph and histogram more visible.

The following scale ranges are possible: 0-1000 / 0-500 / 0-250 / 0-125 / 0-62
